Cboe Global Markets Inc

For 2024 compensation decisions, the Compensation Committee considered competitive market data derived

from a 21-company custom peer group and an executive compensation survey published by a third party that

solely covered exchange holding companies, financial services firms, and technology-focused companies of

similar size to Cboe.

The 21-company custom peer group was composed of exchange holding companies, financial services firms,

and technology-focused companies with corporate profiles similar to ours. The Company's annual revenue fell

near the median of the peer group and the market capitalization and number of employees fell below the

median of the peer group.

The Compensation Committee used the market data derived from the peer group and the executive

compensation survey as points of reference, rather than as the sole determining factor in setting compensation

for our NEOs.

Following the 2024 compensation decisions, the Compensation Committee reviewed the peer group. The

Committee reviewed the data provided by Meridian and compared our corporate performance to our peer group

in the areas of revenues, gross profit, market capitalization, and number of employees. The Committee also

considered business descriptions, complexity of business, and other qualitative factors. The Committee

approved one change to the peer group in 2024, removing Synopsys, Inc. following its recent acquisitions

activity because it no longer had a corporate profile similar to ours. The change decreased the number of peers

from 21 to 20 companies. With respect to the updated peer group, the Company's annual revenue and number

of employees fell below the median of the peer group and the market capitalization fell near the median of the

peer group.
